BIM 환경에서 GPS를 활용한 타워크레인의 철골부재 양중경로 추적 방안 연구

Abstract

As buildings are becoming bigger, higher, and more complex, skilled workers are needed more than ever. But the number of skilled workers is decreasing. The automation of construction processes was suggested as a possible solution. For the construction of high-rise buildings, tower cranes, in particular, are the most important equipment. Our long-term goal is to develop a robotic tower crane. In this paper, as the first step towards the development of a robotic crane development, we tested a possibility of adopting the Global Positioning System (GPS) combing with the Building Information Modeling (BIM) technology in tracking the lifting paths of a tower crane. In order to support the management of lifting processes of construction materials, especially steel frame members, a tower crane simulation system is developed using the GPS and BIM technologies. For the tower crane simulation system, a lifting path tracking system and an object model for a tower crane are developed. We proposed a variation of the relative measurement method in GPS, which uses a pair of regular GPS, and tested the precision of the proposed system in various situations.
